From other Nightclub owners' comments, it appears as though Great White may have a history of setting of pyros without permission.

Certainly from my time working in Uni gigs in the UK, anytime someone wanted to use pyros, there had to be a bucket of sand next to each, and a couple of guys with appropriate extinguishers nearby. I would suspect that a similar requirement would be necessary for the club to get a license for pyros. (Apparantly they didn't have one anyway).

I can quite believe that the club owners would have more of an incentive to follow common sense precautions than the band would, and find it harder to believe that the club owners would have known about the pyros and not provide extinguishers.
